Frerin (Third Age 2751 – 2799, aged 48 years) was a Dwarf of the royal line of Durin's folk. The second son of King Thráin II. His older brother was the Dwarven hero and future king Thorin II Oakenshield, and his younger sister was Dís. With the rest of his family he was driven into exile from the Lonely Mountain when the DragonSmaug sacked the their home. He later took part in the bloody War of the Dwarves and Orcs, even though he was still very young at the time. In the final conflict of the war, the Battle of Azanulbizar, he was in the first assault of the vanguard that was led by his father. Which was thrown back with loss. Frerin and the rest of the vanguard were driven into a wood of great trees near lake Mirrormere. And there Frerin met his end, along with his kinsman Fundin, and many others
were killed.
After the battle, the Dwarves that were left built many pyres, and burned the bodies of the their dead, Frerin being one of them.
